## Summary description

Rittal AS 4051.647 are insulated wire ferrules (aderendhülsen) made with copper sleeves and polypropylene (PP) insulation. Each ferrule has a 3.5 mm outer diameter and 10 mm length, supplied in a pack of 1000. Designed for reliable conductor termination, they ensure consistent crimping, improved contact area and secure connections in electrical panels and control cabinets.

## Long description

Rittal Aderendhülsen AS 4051.647 are insulated wire ferrules combining a copper sleeve with a polypropylene (PP) insulating collar. Each ferrule measures 3.5 mm in outer diameter and 10 mm in length and is supplied in a pack of 1000. These ferrules are intended for conductor termination and crimped connections in electrical panels, control cabinets and terminal blocks where consistent contact area and secure clamping are required.
Advantages
The copper sleeve provides reliable electrical conductivity and resistance to corrosion while the polypropylene insulation ensures stable mechanical protection and easy identification. The standardized dimensions support uniform crimping and repeatable connection quality across multiple conductors. Supplied in bulk packs of 1000, these ferrules are convenient for repetitive installation tasks and reduce the risk of stray strands and loose connections.
Suitable for
 Crimp termination of stranded copper conductors with matching cross-section
 Electrical panels, control cabinets and terminal block connections
 Industrial and commercial wiring where standardized insulated ferrules are required
 Maintenance, assembly lines and installation teams needing bulk quantities
When it may not be suitable
These ferrules are designed specifically for stranded copper conductors; they are not intended for use with solid conductors, aluminium conductors, or connectors requiring non-insulated ferrules. Also, the 3.5 mm outer diameter and 10 mm length are for specific terminal sizes—verify physical fit before use in unusually small or oversized terminals.
Key specifications
 Sleeve material: copper
 Insulation material: polypropylene (PP)
 Outer diameter: 3.5 mm
 Length: 10 mm
 Pack quantity: 1000 pieces
How to use
Strip the insulation from the stranded conductor to the appropriate length, insert the conductor strands fully into the copper sleeve so no stray strands remain, and position the polypropylene collar at the insulation edge. Use a suitable ferrule crimping tool matched to the ferrule size to perform a single, firm crimp until the tool indicates a complete crimp. After crimping, inspect the joint for uniform compression and secure mechanical retention before connecting to the terminal or busbar.
What to consider before purchase
 Confirm compatibility with conductor cross-section and terminal dimensions
 Ensure the insulation type and color meet any identification or coding requirements
 Verify that crimping tools and dies are suitable for 3.5 mm ferrules
 Consider storage and handling of bulk packs to avoid contamination or damage
Usage recommendations
Use dedicated crimping tools with corresponding dies for insulated ferrules to achieve reliable electrical contact and repeatable mechanical retention. For high-vibration or safety-critical applications, perform pull tests and visual inspections as part of quality control. Store packs in a dry environment and handle ferrules with clean hands or gloves to prevent contamination of the copper sleeve.
